VALVE.

SPECIFICATION forming part of Letters Patent No. 637,161, dated November14, 1899.

Application filed January 23 1 8 9 9.

To all whom it may concern.-

Be it known that I, JOHN H. RING, a citizen of the United States,residing at Lowell, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inValves; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to steam, gas, or water valves, and the purposeof the same is to provide a self-adjusting non-leaking valve of thecharacter set forth in such a manner as to simplify and cheapen theconstruction and increase the efficiency of operation.

The invention consists in the provision of a construction whereby whenthe plug or parts coacting therewith become worn out or incapacitated inany manner the same can be readily adjusted, removed, and replaced byothers without necessitating the disconnection of the valve-casing fromthe pipes to 'which it is secured, and also requiring but one quarter orless of a full turn of the device for operating the valve-stem in orderto open or close the valve, and, further, to so arrange the valve as todispense with packing of any character and utilize the positiveoperation of incidental attachments to always hold the plug to its seatand maintain a uniformity of operation.

The invention further consists of the general and detail construction,arrangement, and combination of parts, as hereinafter fully describedand claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional view of the improved valve. Fig. 2 is a transverse verticalcentral section of the same. Fig. 3 is a detail perspective viewof thevalve-plug and a part of the stem. Fig. 4 is a horizontal section,slightly enlarged, on the line w m, Fig. 2. Fig. 5 is a detail sectionalview of a slight modification. Fig. 6 is a vertical longitudinalsectional View of the device embodying a modification. Fig. 7 is a topplan view of the device shown by Fig. 6, showing the stem cut off. Fig.8 is a horizontal section on line a; 00, Fig. 6. Fig. 9 is a similarview on the line 212/ Referring to the drawings, wherein similar SerialNo. 703,139. (No model.)

numerals are utilized to indicate correspond ing parts in the severalviews and now particularly referring to Figs. 1, 2, 3, 4, and 5, thenumeral 1 designates the shell or valvecasing, having threaded openings2 and 3 in a part thereof and horizontally arranged insimilarly-positioned members of the casing for the reception of inletand outlet pipes or an inlet-pipe and dispensing-spout, and with whichalso may be employed a waste-outlet. (Not shown, but fully understood inthe art.) Intermediate of the members containing the threaded openings 2and 3 and rising Verticallyis a hollow head 4, having upper internalscrew-threads 5 in a portion of the same and a circumferential shoulder6 below the threads. The opening in or the hollow portion of the head 4is continuous with a lower frusto-conical opening 7, intermediate themembers containing the screw-threaded openings 2 and 3 and continuingdownwardly into a lower drop 8. The wall of the opening 7 forms a seatfor an elongated plug-valve 9, having a way 10 cut therethrough and anupper beveled head 11, from the center of which a stem 12 rises and isadapted to receive at its upper end a lever, handle, or wheel 13.Between the seat for the said valve and the inner terminations of thescrew-threaded openings 2 and 3 slotted partitions 14 are positioned,and the slots thereof are of the same dimension as the way 10 of saidplug, the latter being alined with the slots in the partitions when thevalve is opened to form a straight and unimpeded passage through thesame. The lower reduced end of the plug-valve 9 bears upon the upper innor surface of the drop 8, and to accurately adjust said valve inopening and closing the same the lever end thereof has a slot 15extending entirely therethrough and fits over and coacts with a verticalstop-pin 16, rising from said surface of the drop and eccentricallypositioned, as clearly shown in Fig. 4. The said pin 16 stands in suchrelation to the lower end of the plug-valve as to positively engagecorresponding portions of the opposite Walls of the slot 15, and theprimary adjustment is such also that it will be im possible to turn thevalve 9 beyond a predetermined point in opening or closing the same andrequiring but a quarter-revolution or less of the lever, handle, orwheel 13 to accomplish either result.

As clearly shown by Figs. 1 and 2, the opening 17 in the head EL islarger than the opening 7 to receive the plug-valve, and the wallthereof is straight, terminating with equal diameter at the shoulder 6.The upper screwthreads 5 of the head 4: surround the inner part of alarger opening or seat in said head, which is adapted to receive a cap18, having a flange 19 to bear on the upper end of said head,screw-threads 20 to articulate with the threads 5, and a circumferentialshoulder 21 to rest on the shoulder 6. The outer face of the flange 19is adapted to be formed with angular faces for engagement of a wrench oranalogous device to remove or apply the said cap,and the stem 12 extendscentrally through the cap.

As shown by Figs. 1 and 2, the cap 18 has an integrallydepending sleeve22, which snugly engages the opening 17 of the head 4, and has a lowerreduced edge 23 to bear on the periphery of the conical head 11 of theplug-valve 9. By the formation of the reduced lower end 23 of the sleevefrictional contact on the head of the valve is materially diminished,and at the same time means for accurately holding said valve in its seatare provided. Vithin the said sleeve 22 and surrounding the stem 12 aspring 21 is mounted and bears on the head 11 of the valve 9. Thepurpose of this spring is to institute a cushion-pressure on, the valveand insure an accurate registration of the way thereof at all times withthe slotted partitions 14': irrespective of the function of the sleeve22.

The cap 18 and the sleeve 22, as shown by Fig. 5, maybe made in twoparts, and in this instance said cap holds the sleeve to its place by anoverpressure, as will be readily seen. By the use of the cap and sleevein either form and the elongated construction of the valve-plug aperfectly steam, water, or gas tight fitting is produced without theemployment of the usual packing, and in addition the valve is heldproperly to its seat. By unscrewing the head 18 suffioiently and drawingupwardly on the stem 12 the plug, spring, head, and sleeve can besimultaneously withdrawn from the casing of the valve withoutdisconnecting the latter. This is especially convenient in readjustingor correcting any irregularities that may become apparent in the valve,and said parts may be as readily repositioned in the casing after repairor other similar parts substituted therefor. This ready withdrawal andinsertion of the parts provides also for conveniently cleaning the valveas an entirety or removing any obstructing material.

The pin 16 in the drop 8 is shown in a position to accommodate a certainmovement of the valve; but it will be understood that a reversal of saidpin might be made to obtain an opposite movement and secure the desiredresult.

To hold the cap 18 against accidental movement after the device isproperly set or adjusted, screws 25 are employed andremovably extendedinto the flange 20. In separating the parts these screws are firstdetached. These screws can also be used from time to time, if need be,to firmly hold the valve by first turning the cap into the casing andafter securing it as before.

In Figs. 6, 7, 8, and 9 a modification of the valve is shown andadapting the same general principles to faucets. In this instance thecasing 26 has but one threaded opening 27, and the bottom of said casinghas in addition a vertical opening 28 therethrough. In the side of thecasing opposite the location of the threaded opening 27 a horizontalslotway 29 is formed, and in this instance also the cap 30 and sleeve 31are the same as in the structure previously described. Screws 32 areemployed to prevent the cap from having self-loosening movement andserve a similar purpose as regards adjustment, as heretofore indicated.In this instance a spring 33 is confined by the sleeve 31 and surroundsthe stem 34 of the plug-valve 35. The opposite terminating ends 36 and37 of said spring are held in en gagement,respectively,with the cap 30and top of said valve, and the valve is by this means automaticallyreturned to normal position in addition to the function of said spring,as explained in relation to former construction. Near the lower end ofthe valve a pin 38 is located and projects outwardly in a horizontalplane and works in the slotway 29 to limit the movement of said plug. Inthe lower part of the plug a way 39 is formed and comprises an upperhorizontal limb 40 and a vertical limb il. lVhen the horizontal limb 40is turned in alinement with the threaded opening 27, water or otherliquid to be dispensed passes down through the vertical limb 4:1 and outthrough the vertical opening 28, and after a preferred or sufficientquantity has been drawn the valve-stem is released and the valveautomatically closed. The sleeve in this form of device also takes theplace of packing and insures a firm seating of the valve subject toadjustment, and also by the general construction a convenient andeifective dispensing-faucet is provided.

Having thus described the invention, what is claimed as new is-- 1. In avalve, the combination of a casing having a valve-seat and a hollowhead, a plug- Valve rotatable in said seat and having a way therethroughand provided with a stem, a cap applied to and closing the upper end ofthe hollow head and having' the valve-stem passing therethrough, anon-rotatable sleeve located in the hollow head and adapted to bear onthe upper end of the valve and interposed between it and the cap, aspring wholly inclosed within the sleeve and surrounding the stem andconfined between the cap and Valve, and a pin projecting inward from thecasing and entering a cut-away portion of the valve to limit itsrotative movement, substantially as described.

' 2. In a valve, the combination of a casing having a valve-seat withalower projection eX- tending eccentrically thereinto, a plug-valveremovably fitted in said seat and having a stem at the upper enlargedend and a slot extending entirely through the lower end and havingopposite parallel walls, said slot receiving the lower projection whichis adapted to contact with the parallel walls of the same,

a cap having an integral non-rotatable pend-
